Abstract: A stomach exercise device includes a pneumatic cylinder incorporating a piston and a handled piston rod. The bottom of the pneumatic cylinder is movably connected to a base through a universal joint which permits the pneumatic cylinder to turn relative to the base. The base can be positioned beneath the two thighs of a sitting exerciser while he moves the piston rod up and down or turn it to and fro so as to alternately bent and straighten or twist the upper portion of his body.

Abstract: This invention provides compositions which are curable to hydrophilic, water-absorbing silicone-organic copolymer elastomers via free radical polymerization such as by the use of free radical precursors, UV or electron beam. The compositions are mixtures of (A) from 50 to 95 parts by weight of block copolymers containing polydiorganosiloxane segments and polyalkyleneoxy segments which block copolymers contain terminal aliphatically unsaturated groups such as those derived from the reaction of isocyanoethyl methacrylate with terminal free hydroxyl groups present on the polyalkyleneoxy segments and (B) from 5 to 50 parts by weight of at least one substantially water insoluble aliphatically unsaturated organic monomer which is compatible with (A) such as methyl methacrylate. The cured elastomers, some of which are optically clear, are useful as membranes for gas or fluid separations or for the controlled release of bioactive agents such as insecticides or herbicides.

Abstract: This present invention provides aqueous emulsions which are capable of depositing coatings and membranes of hydrophilic, water-absorbing silicone-organic polymer elastomers. The elastomers are free radical polymerized copolymers of (A) from 50 to 95 parts by weight of block copolymers containing polydiorganosiloxane segments and polyalkyleneoxy segments which block copolymers contain terminal aliphatically unsaturated groups such as those derived from the reaction of isocyanatoethyl methacrylate with terminal free hydroxyl groups present on the polyalkyleneoxy segments and (B) from 5 to 50 parts by weight of at least one substantially water insoluble aliphatically unsaturated organic monomer which is compatible with (A) such as methyl methacrylate.
